var destination = new Array();

            destination[0] = '4';

            destination[2] = '6';
            destination[3] = '7';
            destination[4] = '8';

// Ext.apply(obj1,obj2) copy all properties of obj2 to obj1 any way,replaceing
// the ones that obj1 has already defined

 Ext.apply(destination,source);
document.write(destination + '<br/>'); // 1,2,3,7,8,9

// Ext.applyIf(obj1,obj2) copy all properties of obj2 to obj1 only if
// they don't already exist
